Dual-band wireless range extender helps eliminate dead spots in your office by extending Wi-Fi coverage up to 7,500 square feet. Cross-band technology maximizes the simultaneous use of both bands for high-speed data transfer and uninterrupted streaming. Simultaneous dual-band technology delivers a stronger connection at a wider range than a single band. Spot-finder technology directs you on finding the right placement for this extender to make sure you're getting the best possible Wi-Fi signal. Audio capability lets you connection to a stereo system or audio speaker and stream music from a mobile device or computer. Universal design works with any wireless router (sold separately) for simple operation.
